To date, hydrogen generators of this type are not deployed in any commercial development. Some proposed solutions for commercial development utilize propeller style turbines mounted on the ocean floor, with processing done either underwater or aboard stationary vessels on the surface. Another solution for hydrogen generation involves using a vessel as a wave style electric generator itself, and processing the hydrogen there as well.
These solutions are expensive and inefficient. Propeller style turbines are subject to breakage and are dangerous to marine life. A fleet of hydrogen production and distribution vessels would consume vast amounts of energy and personnel. These solutions also only allow for a single source of electrical power, thus creating a single point of failure.
Previously no feasible means of processing the resulting byproducts and debris from ocean water purification has been presented. Underwater life support, as well as a product distribution network, are also missing from these solutions.
In accordance with one embodiment, a fully automated hydrogen generator comprises a plurality of energy sources, utilizes that energy for the production of hydrogen from the electrolysis of water, and provides oxygen for life support. Housing for the generator is provided, as well as a distribution means for the commercial consumption of the hydrogen, the oxygen, and the byproducts from the processes.
Advantages of one or more aspects of the Self-Sufficient Hydrogen Generator include, providing a more efficient and comprehensive hydrogen generator that transforms ocean water into hydrogen. The invention described here doesn't harm fish or other marine animals, and has no negative impact on the environment. Other advantages of one or more aspects include providing a more scalable and economically attractive hydrogen generator that doesn't interfere with oceangoing traffic, and is capable of producing vast amounts of hydrogen from renewable resources without relying on diminishing fresh water supplies as other methods of electrolysis normally do. An embodiment located offshore and underwater is easier to secure from intruders, and safe from catastrophic storms, tidal waves, and rising sea levels. These and other advantages of one or more aspects will become apparent from a consideration of the ensuing description and accompanying drawings.
One embodiment of the hydrogen generator 1 is illustrated in
I contemplate the submersible structure 2 be constructed from reinforced, possibly marine grade, concrete, or other suitable materials, and sufficient in size to accommodate all of the apparatus that comprise the hydrogen generator 1. The submersible structure 2 may be fabricated onshore and towed into place by tug boats, and lowered to its ideal position. The apparatus to be included with the structure, such as turbines, electric generators, and electrolyzers may be assembled and installed onshore as well. As seen in
Vertical columns 134, attached to the bottom of the foundation, act as anchors to prevent movement due to use and/or earthquakes, and are depicted in
I contemplate using submersibles, including diving bells, to transport people and materials to and from the facilities. An enclosed road, inside a tube, similar to San Francisco's Bay Area Transit system, would enable personnel and materials to be driven directly into and out of the facility.

Water entering directional funnels 4 and 7 is channeled so as to impact the HOLLOW TURBINE's blades at an optimal angle. The turning HOLLOW TURBINE transfers rotational energy, via rotational energy connecting elements 8, 9, and 10, to rotors 12 and 13 that induce current by rotating their alternating magnetic fields in close proximity to the stators 11 and 14.

Cold water enters the steam condenser 108 through a boiler water intake pipe 109 and is preheated by the cooling steam within the same steam condenser 108. The preheated water enters the boiler 106 through a boiler water intake pipe 110. The resulting steam is channeled by the boiler steam output pipe 107 through the same steam condenser 108 that preheated the incoming water. The resulting superheated purified water enters the insulated electrolyzer 112 through an insulated electrolyzer water input 111. The remainder of the operation is the same as previously disclosed.
Large debris is removed from the entering ocean water by an intake filter 17 before passing through a check valve 18 on the way to an intake pump 19 before arriving at an electrolyzer 43. After a predetermined amount of debris has collected within the electrolyzer 43, the hinged bottom 119 opens to allow the debris to safely fall away from the electrolyzer 43. An alternating magnetic field is generated by an electromagnet 118 and vibrates the electrolyzer to help dislodge any debris stuck within the electrolyzer's inner nonstick coated surface 120.
This embodiment operates the same as above with the exception of energizing the heating element 121 to produce a predetermined temperature.
As previously mentioned, ocean waters enters the system through intake filter 17 and passes through check valve 18, intake pump 19 and a reverse osmosis filtration means 122 before entering electrolyzer 43 through intake pipe 20.

Debris from the boiler 32 falls onto the conveyor belt 36 and travels out of the submersible structure 2 through an exhaust port 37, where the conveyor belt 36 ends, the debris falls down and back into the surrounding ocean water.
Debris falling from the boiler 32 lands on the conveyor belt 36 and is transported into the boiler debris exhaust port 37 where it falls off the conveyor belt 36 and into the ocean. Debris falls from the boiler 23 into the boiler debris collector 38 that feeds the auger style boiler debris removal system 39 that transports the debris through boiler exhaust port 40 and into the boiler debris processing plant 41, where it is processed for export.
Operation of the hydrogen generator 1 in all of these configurations is unaffected by the choice of operating environments.
One embodiment may omit life support systems, including breathable air, thus reducing size and complexity.
The processing necessary for hydrogen generation remains the same.
One embodiment may omit life support systems and on site electric generation greatly reducing size and complexity. The reduced size and complexity may even allow the generator to be easily lowered into place for operation and raised for servicing and replacement.

This embodiment depicts an onshore version of the present invention 1 that includes at least one electrolyzer, not shown, and optional water purification means, also not shown, and connects to the seawater intake pipe 135 and to the residue discharge pipe 136.
Seawater for the facility is pumped in through the seawater intake pipe 135. The residue resulting from operations is discharged through the residue discharge pipe 136. Otherwise the facility's operation is the same as described above.
Operation of this embodiment is the same as in previous embodiments, except with the addition of a means of synchronizing the HOLLOW TURBINES, not shown.
From the description above, a number of advantages of some embodiments of the self-sufficient hydrogen generator become evident:
(a) Large scale hydrogen production is possible, economical, and highly scalable.
(b) Leveraging the kinetic energy of ocean currents and tides, together with the use of ocean water for electrolysis, provides a very effective and efficient hydrogen generator and water purification means, with both methodologies utilizing renewable resources that do not deplete scarce fresh water sources.
(c) Located just offshore and underwater, the hydrogen generator does not obstruct views, require expensive oceanfront property, does not interfere with oceangoing traffic, and will not harm fish or other marine animals, or otherwise harm the local environment in which it is deployed. As such, it is easier to secure from intruders, impervious to extreme storms, tidal waves and rising sea levels. The detached foundation will allow the facility to survive earthquakes, while remaining in place, thanks to its vertical columns acting as foundation anchors.
(d) The debris resulting from the purification or the electrolysis of ocean water is captured, and may be exported, and possibly used to offset the desalination effect of melting glaciers, in locations such as off the coast of Greenland.
Thus the reader will see that at least one embodiment of the hydrogen generator provides for an efficient and environmentally friendly hydrogen generation system that can generate vast amounts of hydrogen. Located just offshore and underwater, the hydrogen generator preserves scenic ocean views, avoids expensive oceanfront property, and provides a secure operational environment.
While the above description contains many specificities, these should not be construed as limitations on the scope, but rather as an exemplification of several preferred embodiments thereof. Many other variations are possible and have been broken down into three categories: process related, structure related, and life support related.
The electrolyzers may be immersed in heated solutions in order to raise and maintain the water's temperature within the electrolyzer. That heated solution may be oil.
The electric power generated on site is best utilized by incorporating three phase electric power. Two and one phase power will also work.
Electromagnets and other devices may be cooled by circulating helium around them, or by circulating any other cooler substance, most likely in liquid form.
Electrodes used in electrolysis may be composed of platinum.
The boilers may further include a scraping means to further aid in debris removal.
In addition to boilers, evaporating plants/evaporators may be used to purify ocean water.
Additional means of exporting the ocean water debris include diving bells and/or an auger style device that lifts the debris to the surface.
The control systems may incorporate other business rules/business logic, and are usually expressed as algorithms. These algorithms may be written in Java, Scala, C, or another appropriate programming language, and embedded within microcontrollers, single board computers, or other information processing appliances. A robotic operating system (R.O.S.) may also be incorporated.
Producers may access weather information, and possibly other external data, and incorporate it into the production forecast models. These models form the basis for expert and decision support systems (DSS) that may be utilized by both producers and clients to produce dynamic contracts that form another module in an enterprise resource planning system (ERP).
Sun's Java Real-Time System (Java RTS) is a mature technology that is well suited for control systems.
Scala is a hybrid functional and object-oriented programming language that can leverage its higher level of abstraction to take full advantage of the parallelism in modern, multicore systems. It's designed for concurrency, expressiveness, and scalability. Other functional programming languages, such as Erlang, may also be utilized.
Multiple technologies for application integration have included: remote procedure call (RPC), Common Object Request Broker Architecture (CORBA), Distributed Component Object Model (DCOM), .NET remoting, Enterprise Java Beans (EJBs), Java EE Connector Architecture (JCA), Java Web Start, and Java Remote Method Invocation (RMI). A newer technology for application integration is Java Business Integration (JBI).
One possible means of enterprise application integration incorporates a service oriented architecture (SOA). Application integration enables disparate systems to communicate, and in one embodiment it orchestrates the business processes between producers and clients. SOA may also be leveraged for communication between the control systems within the hydrogen generator itself. An enterprise service bus (ESB), including web services, is one means of incorporating a SOA. These technologies are part of an enterprise information system (EIS).
Technologies, at the time of this patent application, of a SOA platform may include, but are not limited to: business process management (BPM), enterprise decision management (EDM), enterprise service bus (ESB), event stream processing (ESP), message-oriented middleware (MOM), a registry/repository, service components and compositions, and web service mediation (WSM).
The control systems may utilize web services without conforming to the restrictions of a SOA.
There are three ways to implement a service: as a component, as a Web Service, and as a REST service.
There are four integration architectures: Point-to-Point, Hub-and-Spoke, Enterprise Message Bus, and Enterprise Service Bus.
Services, including message oriented middleware (MOM), may be hosted independently on application servers and enable business-to-business integration. Web servers may be utilized to provide an interface to these applications. Database management systems (DBMSs) will act as data repositories for plant operations and transactions management.
Networking topologies may include, but are not limited to, local area networks, wide area networks, metropolitan area networks, the Internet, and intranets. These networks, internal and distributed, may be wired or wireless.
These technologies, and possibly others, are integrated to provide “intelligent auctions” that feature open, automated-bidding between producers and consumers.
Producers will be able to signal consumers when it is time to begin and time to end extracting resources from the pipelines, while ensuring that producers don't produce more products than can be consumed.
Data, as well as network access, backup means, local and remote, are also incorporated.
Data encryption is used to secure data locally and remotely. The encryption system may include, but is not limited to: Symmetric-key ciphers, and/or Asymmetric-key algorithms, and/or Shared-Secret algorithms (all may have wide keys), and a combination of asymmetric and symmetric key encryption.
Distillation may be performed by either batch or continuous processing.
Both state and federal regulators may utilize these technologies to monitor ongoing processes.
The invention is also a candidate for incorporating the principle of a BUOYANT GENERATOR. As described in the U.S. Pat. No. 7,348,686 B2, a BUOYANT GENERATOR incorporates flotation devices that reduce the vertical loads on bearings, allowing for greater efficiency, stability, and product life cycles.
DC motors, servomechanisms, including servomotors, stepper motors, actuators, including linear and rotary, hydraulics, including hydraulic cylinders, sensors, robotic arms, and other mechanisms control the moving elements of the generator and its facilities. AC motors, especially three-phase AC motors, may be utilized for any heavy lifting. Microcontrollers may be used for real-time processes and processing and may incorporate object-oriented architectures, as well as a robotic operating system (R.O.S.).
A single master controller may orchestrate the entire process, possibly in a one-to-many architecture resulting in a fully automated hydrogen generator.
Single board computers (SBCs) may be incorporated.
A communications buoy may also be necessary.
The previously referenced HOLLOW TURBINE may further include intake and exhaust pipes within the turbine's cylinder that prevent entering and exiting flows from adding weight and drag to the turbine. An optional directional cone and its helical supports may channel incoming water in a direction perpendicular to the outermost and efficient portion of the turbine's blades and may be fastened within the intake pipe directly before the turbine's blades.
A turbine steering means may be employed to maximize the turbine's efficiency.
Hydraulics may be used where appropriate and remotely operated vehicles, autonomous underwater vehicles, and hybrid remotely operated vehicles may be useful for outside maintenance. Operators may be stationed within the submerged plant, or remotely from onshore, or aboard a vessel.
Built in cameras, microphones, and speakers may be necessary for efficient operations.
The invention's boilers, transfer pipes, condensation tubes, and electrolyzers all may benefit from being covered in insulation.
The foundation may be extended laterally to compensate for structural shifts due to seismic events.
The structures and attached components may include a copper/nickel veneer (70/30 respectively is one common ratio) to resist corrosion from saltwater, and to protect from barnacles and other marine life. Paint with copper added may also be used.
Attaching an electrified grate or screen (regularly energized for short periods of time) to openings and/or wire cloth to structures, will help prevent jelly fish and other marine animals, including barnacles, from clogging inlets and attaching to other parts of the structure. A structural coating may also be utilized to repel ocean life.
Sliding panels, or other constricting means, functioning like an aperture in a camera, may be incorporated to seal or regulate the turbine's water intake and discharge openings.
Localized dredging will increase the energy of the waves and flows around the installation that will increase the efficiency of the facility's turbine.
Tunnels bored into the earth's crust, or tubes, sufficient in size and extending from the shoreline, may also provide access to the underwater facilities.
Incoming ocean water may be circulated through pipes embedded within the structure's walls and/or floors, in order to cool the facility where needed.
Likewise, heated water from distillation or by other means may also be circulated through pipes embedded within the structure's walls and/or floors, in order to heat the facility where appropriate.
Additional electric power may also be obtained by solar thermal and solar cell installations mounted on a buoy. The same buoy may also be utilized for importing atmospheric air for life support. This is how the NOAA submersible lab acquires its air and electrical power.
A smaller, possibly portable, version of the present invention, without life support and/or desalination apparatus, may be used for other applications. For in stream versions, the unit may be constructed from titanium covered carbon fiber composites.
Installations of the present invention off the Southern California coast, and/or the Gulf of California, may provide enough hydrogen to supply the water and electricity needs of present and yet to be built cities in the southwestern states. Electricity for the offshore generators described here may be secured from the grid or from solar power projects in the same deserts that will benefit most from these hydrogen generators. The same corridors of land that would provide the necessary space for electric transmission lines could also be utilized to provide the space necessary for the returning hydrogen pipelines. Providing a new source of fresh water to Southern California will allow more of the High Sierra runoff to remain in the San Joaquin Valley where it can be used for agricultural products.
A means of oil and water separation may be necessary in some cases. At least one storage tank may be incorporated to allow oil to rise to the upper regions of said tank where it may be removed, in a process known as sedimentation. Evaporation, perhaps by distillation, is another means of removal. Introducing certain bacteria to a tank of oil laced ocean water, under the right conditions, will enable the microbes to eat the oil. Dispersants may help the microbes in the process by reducing the oil to droplets. Centrifugation and membrane separation are other means for removing oil from water. Two other technologies are Vertical Tube Coalescers, from the U.S. Army, and Vessel Internal Electrostatic Coalescers, from offshore-technology.com.
Offshore solar power, photo voltaic or solar thermal, located on an old oil platform or floating barge, may completely supply electric power, or supplement other means.
Life support systems may or may not be present in all embodiments.
Purified ocean water may also be used for human consumption.
Waste management facilities may be incorporated into the facilities.
Employee facilities, including locker rooms, showers, kitchen facilities, and lounges may be added, perhaps in a secondary structure. Such facilities may form the basis for an underwater city.
Nitrogen may be imported via pipelines directly within the structure or stored, perhaps as a liquid, elsewhere within the facility.
Nitrous oxide may also be mixed into the circulated air, if necessary, for life support.
Breathable air, circulated by a blower, maybe imported directly from the ocean's surface or from onshore.
Temperature for the facility may be provided by circulating water, hot or cold, perhaps harvested from the system's processes, through pipes embedded within the structure's walls, ceilings, and/or floors.
The invention may form the basis for an underwater complex.
